The main cause of permanently huge tonsillar hypertrophy is chronic, repeated immune stimulation. When the tonsils are repeatedly exposed to bacteria, viruses, or environmental irritants, their infection-fighting white blood cells (lymphocytes) multiply rapidly. Over time, this repeated activity causes the tissue to hypertrophy (grow) permanently, even after the initial illness has cleared
A rabies vaccine does not cause a "white blood cell infection." Because it is a killed-virus vaccine, it cannot give you the disease. However, the vaccine stimulates your immune system, which can cause white blood cell counts to temporarily shift (such as lymphocytosis or leukocytosis) and occasionally causes swollen lymph glands as your body builds immunity
Yes, tonsils are part of the lymphatic system. They act as secondary lymphoid organs and serve as your immune system's first line of defense, trapping viruses and bacteria that enter through your nose and mouth
